All Rovers are a bit of a mare when it comes to remapping - talk with Moto Build racing though - the ICON piggyback ecu might be the answer you are after.

I'm not sure a BOV or DUMP valve would be a good option on a Diesel Turbo engine, because the ecu might get confused that some of the air is missing from the system.
